Hi Natalie!
Interesting. Try this:
OnWindowResize
Move (highlight) to x: [[Window.width * 5/12]], y: [[Window.height * 7/12]]
If you are specifying placement based on the center point of the highlight, subtract half the width/height of the Target. E.g.
Move (highlight) to x: [[Window.width * 5/12 - Target.width/2]], y: [[Window.height * 7/12 - Target.height/2] ]
